GASEOUS FUEL.

Ho Drawing.

of California, have invented new and'useful Improvements in Gaseous.Fuel, of which the following is a specification. I

This invention relates to a hydrocarbon fuel, and. particularly pertainsto a liquid fuel for use in internal combustion engines and a method ofproducing the same. a

It is the principal object of the present invention to provide a liquidcompound which may be satisfactorily used as a substitute for commercialgasoline in providing a fuel for explosive engines, said compoundpossessing all of the desirable qualities of gasoline and like mineralhydrocarbon oils, and, at the same time, being of such a character as tobe independent of mineral oil shortage.

The present invention contemplates the use of a liquid fuel comprisingproper'proportions of a light grade hydrocarbon oil of vegetablederivation, a solvent therefor, which, at the same time, supplies thedesired oxygen ingredient to the mixture and a volatile diluting agent.

In producing a substitute for gasoline and other like hydrocarbon fuelsit is desirable to provide a' gaseous fuel which does not have anexcesslve water content, is non-corrosive, and practically smokeless andordorless, while possessing a high flash point and producing at least anequivalent of power. With these requirementsin mind, a liquid fuel hasbeen produced and is embodied in the present invention comprising alight grade hydrocarbon oil, such as oil of eucalyptus, oil of cedar andturpentine, a solvent for said hydrocarbon oil, such as ether, acetoneor amyl-acetate, and a suitable explosive diluting agent, as alcohol. Incarrying out this invention, it is to be borne in mind that refinedchemicals are not necessary and that, in each instance, raw or low gradeingredients may be used. These ingredients may be mixed in any suitableproportion, although experiment has proven that the followingproportions are approximately correct:

1 part light grade hydrocarbon oil 2 parts solvent I 3 parts dilutingagent. In mixing the ingredients, the hydrocarbon oil and the solvent,such as ether, are

first mixed together. The ether will act to out the oil and disintegratethe molecules Specification of Letters Patent.

'the solvent administered last, a cloudy,

stratified liquid wouldresu-lt. When the ingredients have been properlymixed a de-- sirable combustible liquid will be produced. It is wellknown that the use of heavy grade vegetable hydrocarbon oils as gaseousfuel will result in an objectionable carbon deposit within the enginecylinders. It is also known that ether is objectionable for use alone,due to its prohibitive cost and its high volatile nature. Theseobjections are, however, obviated by the combination 'of the ingredientsin the fuel here described, and, in addition, new results are obtained,as, for example, the excessive carbon content of the vegetable oilcombines with the oxygen content of the ether to insure thatsubstantially .all of the carbon molecules of the gaseous fuel will beburnt at the time of the explosion. It is also possible to'produce ahydro- Patented June 2'7, 1922.

carbon fuel having a desirable high flash .point, due to the alcoholcontent of the mixture. It will thus be seen that by the proper mixingand proportion of ingredients forming the elements of the presentinvention a very desirable volatile fuel maybe produced, and, due to thefact'that this fuel may be made from low grade stock, competition may behad with commercial gasoline.

Having thus described my invention, what I claim I, and desire to secureby Letters Patent is:

1. A liquid fuel consisting of one part of a hydrocarbon vegetable oiland three parts of alcohol, and two parts of an oxygen supplyinghydrocarbon compound which also acts to blend the ingredients.

2. A liquid fuel composed of turpentine,

ether andalcohol.

3. A liquid fuel consisting of one part of a hydrocarbon vegetable oil,two parts of ether'and three parts'of alcohol. In testimony whereof Ihave hereunto set my hand in the presence of two subscribing w tnesses.
